A suspended mallet roll is usually played if a shaking sound is desired on a bass bell. The singing bell technique creates a sustained pitch similar to the sound a wineglass makes as its rim is rubbed with a wet fingertip and is accomplished in much the same way. A short wooden dowel is touched to the outside of the rim of a handbell which is ...
where p rms is the root mean square of the measured sound pressure and p ref is the standard reference sound pressure of 20 micropascals in air or 1 micropascal in water. [34] Use of the decibel in underwater acoustics leads to confusion, in part because of this difference in reference value. [35] [36]
Historically, a bell would be rung on three occasions around the time of a death. The first was the "passing bell" to warn of impending death, followed by the death knell which was the ringing of a bell immediately after the death, and the last was the "lych bell", or "corpse bell" which was rung at the funeral as the procession approached the church.

This produces the brightest and purest sound, which is the attractive sound of a good bell. Much effort has been expended over the centuries to find the shape which will produce the harmonically tuned bell. The accompanying musical staves show the series of harmonics which are generated when a bell is struck.
Peal board in St Michael and All Angels' church, Penkridge, Staffordshire, recording the first peal on the new bells in 1832. In campanology (bell ringing), a peal is the special name given to a specific type of performance of change ringing which meets certain exacting conditions for duration, complexity and quality.
The Angelus, depicting prayer at the sound of the bell (in the steeple on the horizon) ringing a canonical hour.. Oriental Orthodox Christians, such as Copts and Indians, use a breviary such as the Agpeya and Shehimo to pray the canonical hours seven times a day while facing in the eastward direction; church bells are tolled, especially in monasteries, to mark these seven fixed prayer times.
Although ringing up certainly involves some physical exertion, actual ringing should rely more on practised skill than mere brute force. Even the smallest bell in a tower is much heavier than the person ringing it. The heaviest bell hung for full-circle ringing is in Liverpool Cathedral and weighs 82 long cwt 0 qr 11 lb (9,195 lb or 4,171 kg).
The thickness of a church bell at its thickest part (the "sound bow") is usually one thirteenth its diameter. [11] If the bell is mounted as cast, without any tuning, it is called a "maiden bell". Russian bells are treated in this way and cast for a certain tone. [11] Cutaway drawing of a bell, showing the clapper and interior.
